Item Description

Original Item: Only One Available. This is an exceptionally rare inert demilitarized genuine Japanese Type 99 Hand Grenade. This example is offered in very good condition complete with fuse, detonator, original top cap, and even the original safety pin with attached pull string. Removing the pin allows the fuse to be pushed down, which originally would have armed the grenade. This example disassembles for inspection, with the fuze still able to unscrew. It does look to have had the body an fuze color repainted post war for display purposes.

Close examination shows that the the bottom of the fuze is visibly dated with 8 七 十 昭. This marking is written right to left, and would be read: SHOWA (current reigning emperor) Juu-Nana Nen (17th year of reign - 1942) 8th month (August).

There are also markings on the detonator tube in Japanese, which indicate the delay length: 四 - 五 秒 . This is read top to bottom, and is read "Yon - Go Byou", or 4-5 Seconds.

The Type 99 Hand Grenade (九九式手榴弾 Kyūkyū-shiki Teryūdan), also known as Kiska grenade by the American Army was an improved version of the Type 97 fragmentation hand grenade used by the Imperial Japanese Army and Imperial Japanese Navy SNLF during World War II.

History and development
Soon after introduction of the Type 97 hand grenade to front line troops, a number of problems arose. Instability and inaccuracy of the fuse mechanism made the Type 97 almost as much of a menace to the thrower as to the recipient. Furthermore, the Type 97 was a hand grenade and could not be used with grenade launchers. In 1939, the Army Technical Bureau developed an improved version intended to remove these flaws.

Design
The Type 99 hand grenade could either be thrown by hand or fired from a Type 100 grenade discharger. Unlike the earlier Type 91 or Type 97 grenades, the body was not segmented, but was smooth and flanged on both ends. It was also slightly smaller in diameter than the Type 91.

Operation required first removing the safety pin by pulling the cord to which it was attached and then striking the head of the fuse on a hard object, such as a rock or combat helmet, and throwing immediately. Since the firing pin was integral no screwing or unscrewing of the firing pin holder was necessary, as with earlier model Japanese grenades. The Type 99 could also be used as a booby trap by removing the safety pin and setting under a floorboard or chair.

Combat record
The Type 99 was issued as a standard rifle grenade to Japanese infantrymen in the Second Sino-Japanese War and throughout the various campaigns of World War II. The first examples to fall into the hands of Allied military intelligence were captured at the Battle of Kiska in the Aleutian Islands, which gave rise to the nickname of “Kiska grenade” by American troops.
